Three dead endangered Coromandel brown kiwi have been discovered at Tairua, Whenuakite and Matarangi in the past few months.

DoC biodiversity ranger Mailee Stanbury said at one stage five dogs were seen roaming the Whenuakite block.

The message to owners was simple.

"Obey the signs and if an area says don't bring in dogs then please be respectful of those signs," Stanbury said.

"Please keep your dog in sight at all times, know where your dog is, keep them under control and preferably on a leash or at least under verbal control."

There were not many areas in the Coromandel closed to dogs and Whenuakite was the only area closed to hunting with dogs, she said.

"So there are a lot of places that you can still go with your dog."

It was not unusual to find kiwi out and about during the day in summer foraging for food, Stanbury said.

"Particularly coming into summer when it gets warm and dry and the ground gets really hard they may have to forage not just at night. They may not have got enough to eat at night and they may be out during the day looking for food and water.

"At any time, there could be kiwi out there."

Kiwi did not stand a chance against dogs, which was their biggest threat, Stanbury said.

"The kiwi actually has a very fragile chest because they are flightless and they don't have big wing muscles, which means they are quite vulnerable."

DoC suggested all dog owners going into kiwi habitat should get kiwi aversion training for their dog.

It takes about 10 minutes, is free and uses a stuffed mounted kiwi.

"It uses a mild electric shock on a collar that at least reduces the chance of a dog going after a kiwi."
